The content of the aforementioned applications, including any intervening amendments thereto, are incorporated herein by reference.

TECHNICAL FIELD

The present application relates to a mascara.

BACKGROUND

A mascara is a type of cosmetics used by women to give their eyes a beauty, and used to apply a mascara liquid in various colors to eyelashes.

Generally, a mascara includes: a container for accommodating a mascara liquid; a handle for opening and closing the container; a rod-shaped brush rod protruding to a lower part of the handle; and a brush formed in the brush rod, which combines with or separates from the container through the handle, wherein the mascara liquid is applied to the brush.

Generally the brush of the mascara is made to realize various functions, such as making eyelashes plump (volume, which has an effect of making eyelashes look dense), curl (having an effect of making ends of the eyelashes warping upwards), slenderness (long lash, which has an effect of lengthening the eyelashes), or clear (having an effect of preventing eyelashes from clumping), according to length and shape of bristles,

With the development of modern society, everyone, regardless of age and gender, gradually pays more attention to appearance, and hopes to look more attractive. Makeup is used as a way to highlight dominant parts of body and make up or cover up weak or unsightly parts.

Makeup cosmetics are cosmetics that apply colors on body parts such as face and nails to compensate for imperfections of skins and highlight advantages of skins, having effects of making the skins look healthier and more attractive, making the appearance look more beautiful and protecting the skins from harmful environments such as air pollution and ultraviolet rays, and having psychological effects of giving satisfaction and self-confidence through self-image and personality expression, social self-protection, and makeup.

Makeup cosmetics can be divided into three types: first, base makeup products are used to make facial skin color uniform and cover up blemishes such as dark spots and freckles, so as to present a clear feeling; second, brightening makeup products are used to apply colors on lips, eyes, nails, etc. to give a three-dimensional impression, make contours clearer, and look more beautiful; third, finishing makeup cosmetics are used to refine makeup on the basis of the makeup to make the three-dimensional effect more obvious and complete the makeup.

Eyelashes, which are often considered to perform aesthetic functions of eyes, protect the eyes. Eyelashes protect the eyes from dust and small insects in the air, so upper eyelashes are longer and thicker than lower eyelashes. Generally, a growth rate of eyelashes is about 0.18 mm per day which is about half of a growth rate of hair. In addition, the eyelashes have a short life span and fall off within 100-150 days. When used correctly, mascara has effects of making the eyelashes look darker, making the eyes become larger and brighter, and can be used as an effective tool to emphasize the eyes. The effects of the mascara can be roughly divided into three types: slenderness effect, dense effect and curl effect.

In modern society, it is hoped that a product with multiple functions will replace a single product with a single function in order to achieve more economy and efficiency. Therefore, in order to adapt to a trend of makeup cosmetics, more efficient multi-products have appeared.

FIG. 3 is an enlarged view showing part A of a mascara according to another embodiment of the present application.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Hereinafter, embodiments of the present application will be described in detail with reference to the drawings, so that those skilled in the art can easily implement the embodiments. However, the present application is not limited to the illustrated embodiments, and can be implemented in many different ways. Moreover, in order to clearly explain the present application in the drawings, parts irrelevant to the description are omitted, and a same part is demonstrated by using a same reference numeral in the specification.

Throughout the description, when describing a certain part “comprise/include” a certain element, it does not mean to exclude other elements, but means to include other components, unless specifically stated otherwise. In addition, a similar element is demonstrated by using a similar reference numeral in the specification.

FIG. 1 is a view showing an overall structure of a mascara according to an embodiment of the present application.

As shown in FIG. 1, a mascara according to an embodiment of the present application may generally include: an upper structure 10 configured to accommodate a brush rod; and a lower structure 20 configured to accommodate a mascara liquid.

The upper structure 10 of the present application may include: a handle portion 11 for providing a space that a user can grasp; a sealing portion 12 for making the upper structure 10 combine with or separate from the lower structure 20; a brush rod 13; and an uneven part 14 provided at one end of the brush rod 13 and immersed in the mascara liquid 30. When the upper structure 10 is combined with the lower structure 20, the mascara liquid accommodated in the lower structure 20 can be prevented from leaking to the outside by the sealing portion 12.

The brush rod 13 and the uneven part 14 of the present application may have a surface made of metal.

Specifically, the brush rod 13 and the uneven part 14 may have a surface made of metal when they are entirely made of metal; or they may have a surface made of metal when they have an interior made of a synthetic metal and a metal coating provided on an outer peripheral surface thereof; or they may have a surface made of metal when they have an interior made of metal and other metal coatings provided on the outer peripheral surface thereof

Therefore, the brush rod 13 and the uneven part 14 of the present application are made of metal, and thus being able to clean the mascara liquid stained on the brush rod 13 and the uneven part 14 or solidified on the brush rod 13 and the uneven part 14 according to user' needs.

The mascara of the present application may also have the problem that the mascara liquid would solidify as the water inside the mascara liquid evaporates, which is the same as the existing mascara. However, since the outer surfaces of the brush rod 13 and the uneven part 14 of the mascara of the present application are made of metal, the mascara liquid containing oil can be more easily cleaned.

Therefore, according to user's needs, the mascara liquid stained on the brush rod 13 and the uneven part 14 or solidified on the brush rod 13 and the uneven part 14 can be cleaned by spraying water on the brush rod 13 and the uneven part 14 or by using only a wet wipe, which is different from the existing mascara.

In addition, the mascara liquid 30 has a main principle of attaching cellulose contained in the mascara liquid to eyelashes of the user, thereby lengthening the eyelashes of the user, which is different from the existing mascara brushes having a structure similar to the eyelashes of the user. The uneven part 14 of the present application only provides a space for accommodating the mascara liquid 30 and the user's eyelashes, and has the surface made of metal, so it has an effect of increasing the adherent degree that the cellulose in mascara liquid 30 adheres to the user's eyelashes.

Furthermore, the brush rod 13 of the present application can be disassembled from the upper structure 10.

As described above, the brush rod 13 of the present application has an outside made of metal, so it can actually be used permanently. However, when the brush rod 13 can no longer be used due to an unexpected situation such as the metal surface of the brush rod 13 falling out, only the brush rod 13 need be replaced.

In addition, when the mascara liquid 30 is completely exhausted, the mascara can be continually used only by purchasing the lower structure 20 containing the mascara liquid 30 separately.

Therefore, not only the overall mascara with the upper structure 10 combined with the lower structure 20 can be produced and sold, but also the lower structure 20 and the brush rod 13 products can be produced and sold separately, thereby having an effect of increasing the value of economic utility.

The uneven part 14 of the present application can be formed to have fine uneven portions, which is different from the existing mascara brush which protrudes from a center of the brush rod 13 at a height corresponding to a length of the eyelashes.

Therefore, there is no case where the user hurts his eyes with the brush at an end of the brush rod. The mascara liquid can be applied from a root of the eyelashes by using the mascara of the present application.

In particular, since a plurality of uneven portions of the even part 14 are formed at 360° on an entire peripheral surface of the brush rod, it realizes an effect of applying the mascara liquid from the root of the eyelashes to the desired area of the eyelashes even for a new user.

In addition, the uneven part 14 may have a length of 10-35 mm.

By setting a length of the uneven part 14 to 10-35 mm, there is an effect that the user can immerse the uneven part 14 to a proper amount of mascara liquid required for applying the mascara.

The above length of the uneven part 14 is only described as an example for convenience of explanation, and may be variously changed according to the user's needs, and does not limit a protection scope of the present application.

On one hand, the uneven part 14 of an embodiment may be provided to protrude or sink from the outer peripheral surface of the brush rod 13 as long as it is immersed in the mascara liquid while accommodating the user's eyelashes in the uneven part. The uneven part 14 can be changed in various ways by user, which does not limit the protection scope of the present application.

The lower structure 20 of the present application may include: a liquid scraping member 21 for scraping off contents of the even part 14 attached to the brush rod 13; a shoulder 23 for fixing to the liquid scraping member 21; and a mascara liquid accommodation part 25 for accommodating the mascara liquid 30.

In the present application, the shoulder 23 may be composed of one or more selected from the group consisting of polypropylene (PP), polyethylene (PE), acrylonitrile-butadiene-styrene plastic (ABS), and acrylonitrile styrene (AS), polyethylene terephthalate (PET), polyethylene terephthalate glycol (PETG), polycyclohexylene dimethylene terephtalate acid (PCTA) and nylon. Preferably polypropylene (PP) or polyethylene (PE) can be used for easier fastening of the liquid scraping member. Polypropylene and polyethylene have good thermal adhesiveness, thus having improved sealing performance and productivity, and further have high flexibility, thereby achieving excellent sealing properties when the cover is locked.

FIG. 2 is an enlarged view showing part A of a mascara according to an embodiment of the present application.

As shown in FIG. 2, the uneven part 14 of the mascara according to an embodiment may have a circular cross section, and may be helically disposed on an outer peripheral surface of the brush rod 13.

The brush rod 13 of the present application may have a diameter D of a cross section in the range of 1.5-7 mm, more preferably 3-4 mm.

When the brush rod 13 has a diameter D of a cross section less than 1.5 mm, the uneven part 14 has a too small size, which makes it difficult to accommodate the mascara liquid 30 and the user's eyelashes. Therefore, it cannot perform a normal function as a mascara. While when the brush rod 13 has a diameter D of a cross section above 7 mm, the uneven part 14 has a too large size, which may cause the user's eyelashes to clump.

A height difference (hereinafter, referred to as “height H of the uneven part”) between the highest point and the lowest point of the uneven part 14 of the present application is 0.1-3.5 mm, and more preferably 0.3-0.5 mm.

When the height H of the uneven part is less than 0.1 mm, the user's eyelashes cannot be placed between the uneven part 14 and may move between the plurality of uneven portions of the uneven part 14, so it is difficult to apply the mascara liquid 30 on the user's eyelashes, while when the height H of the uneven part exceeds 3.5 mm, the eyes may be injured when the user applies the mascara liquid 30 to the root of the eyelashes.

A distance (hereinafter, referred to as “pitch P of the uneven part”) from the highest point to the next highest point of the uneven part of the present application is 0.1-5 mm, more preferably 0.4-0.6 mm.

When the pitch P of the uneven part is less than 0.1 mm, the distance between the uneven potions of the uneven part 14 is too narrow, thus the user's eyelashes cannot be placed, so it is difficult to apply the mascara liquid 30 to the user's eyelashes. When the pitch P of the uneven part exceeds 5 mm, the distance between the uneven part 14 is too wide, thus the user's eyelashes will be clumped.

The cross section of the uneven part 14 of the present application may have inclined parts on both sides thereof. An angle (hereinafter, referred to as the “angle θ of the inclined part”) formed by a right inclined part of a first uneven potion and a left inclined part of a second uneven potion on the right to the first uneven potion may be 30-70°, more preferably 40-60°.

When the angle θ of the inclined part is less than 30°, there is no problem in accommodating the eyelashes of the user, but an amount of the mascara liquid 30 accommodated in a space between the uneven part 14 may be insufficient, resulting in the mascara of the desired degree cannot be realized. When the angle θ of the inclined part exceeds 70°, there is a problem that an excessive amount of the mascara liquid 30 is accommodated in the space between the uneven portions of the uneven parts 14.

FIG. 3 is an enlarged view showing part A of a mascara according to another embodiment of the present application.

As shown in FIG. 3, the part A of the mascara of another embodiment has substantially the same diameter D of a cross section, height H, pitch P of the uneven part 14, and angle θ of the inclined part as those of the part A of the mascara of the embodiment shown in FIG. 2. Hereinafter, only differences from the uneven part 14 of the embodiment described in FIG. 2 will be described.

The uneven part 14 shown in FIG. 2 is arranged helically with the brush rod 13 as a center. However, the uneven potions of the uneven part 14 formed in the mascara according to another embodiment shown in FIG. 3 is provided at a predetermined interval and parallel in the cross section, which is a structural difference.

Therefore, since a plurality of uneven portions provided in the uneven part 14 have respectively parallel sides, when the user uses the mascara of another embodiment, the user's eyelashes with straight hair can be more stably accommodated between the plurality of uneven portions.

The brush rod 13 of the present application may have a diameter D of a cross section in the range of 1.5-7 mm, more preferably 3-4 mm.

When the brush rod 13 has a diameter D of a cross section less than 1.5 mm, the uneven part 14 has a too small size, which makes it difficult to accommodate the mascara liquid 30 and the user's eyelashes. Therefore, it cannot perform a normal function as a mascara. While when the brush rod 13 has a diameter D of a cross section above 7 mm, the uneven part 14 has a too large size, which may cause the user's eyelashes to clump.

A height difference (hereinafter, referred to as “height H of the uneven part”) between the highest point and the lowest point of the uneven part 14 of the present application is 0.1-3.5 mm, and more preferably 0.3-0.5 mm.

When the height H of the uneven part is less than 0.1 mm, the user's eyelashes may not be placed between the uneven part 14 and may move between the plurality of the uneven potions of uneven parts 14, so it is difficult to apply the mascara liquid 30 on the user's eyelashes, while when the height H of the uneven part exceeds 3.5 mm, the eyes may be injured when the user applies the mascara liquid 30 to the root of the eyelashes.

A distance (hereinafter, referred to as “pitch P of the uneven part”) from the highest point to the next highest point of the uneven part of the present application is 0.1-5 mm, more preferably 0.4-0.6 mm.

When the pitch P of the uneven part is less than 0.1 mm, the distance between the uneven part 14 is too narrow, thus the user's eyelashes cannot be placed, so it is difficult to apply the mascara liquid 30 to the user's eyelashes. When the pitch P of the uneven part exceeds 5 mm, the distance between the uneven part 14 is too wide, thus the user's eyelashes will be clumped.

Due to the structural difference of the plurality of uneven portions provided in the uneven part 14, it is necessary to readjust the previously defined angle θ of the inclined part.

The angle θ of the inclined part of the uneven part 14 of another embodiment of FIG. 3 is defined as follows.

The uneven part 14 may include a first uneven portion 141 and a second uneven portion 143, and a flat portion 145 disposed between the first uneven portion 141 and the second uneven portion 143.

When a highest point A1 of the first uneven portion 141, a middle point A3 of the flat portion 145, and a highest point A2 of the second uneven portion 143 are sequentially connected, an angle formed by ∠A1A3A2 can be defined as the angle θ of the inclined part.

According to such angle θ of the inclined part, the cross section of the uneven part 14 of the present application may have inclined parts on both sides thereof. An angle (hereinafter, referred to as the “angle θ of the inclined part”) formed by a right inclined part of the first uneven portion and a left inclined part of a second uneven portion on the right to the first uneven portion may be 30-70°, more preferably 40-60°.

When the angle θ of the inclined part is less than 30°, there is no problem in accommodating the eyelashes of the user, but an amount of the mascara liquid 30 accommodated in a space between the uneven part 14 may be insufficient, resulting in the mascara of the desired degree cannot be applied. When the angle θ of the inclined part exceeds 70°, there is a problem that an excessive amount of the mascara liquid 30 is accommodated in the space between the uneven portions of the uneven part 14.

On one hand, the cross section of the plurality of uneven portions of the uneven part 14 of FIG. 2 is shown in a triangular shape, and the cross section of the plurality of uneven portions of uneven part 14 of FIG. 3 is shown in a semicircular shape, but this is only for convenience, and should be noted that the shape of the cross section of the plurality of uneven portions of the uneven part 14 can be changed in various ways according to the user's needs, and does not limit the scope of the present application.

The above embodiments are used to describe the present application, but are merely illustrative and do not limit the present application. It can be understood that those skilled in the art may perform each of the non-illustrated variations and applications without departing from the essential characteristics of the present application. For example, each element specifically appearing in the embodiment may be modified and implemented. Furthermore, such differences related to the variations and applications can be interpreted as encompassing the scope of the present application determined by the claims.
